August updates


Come visit our CAVERN table at the Blackberry COBBler event on 24 August. We may have FRS and GMRS radios, and possibly even CAVERN tee shirts available (for a tax-deductible donation to support the project).

CAVERN Radio Checks continue weekly on Saturdays at 1:00PM (and sometimes at 8:00AM for sparrows), and we’re also now doing a new Radio Check on Wednesdays at 6:30PM during fire season. Thanks to Larry S, we have a good repeater high over Cobb where a lot of people can reach it by radio. Mel and I are hoping to expand this with two more repeaters once we solve the “tone problem”. If you are a radio nerd and can help us with that, please email me at <dave [at]>.

Meanwhile, we’re working on some prototypes of the first mesh network nodes. (see photo). They are magnificently crude, but we will be testing them in 2019. If you get a tee shirt, you’ll be signed up to help test a very early prototype of the mesh node.


The first three CAVERN mesh network node prototypes starting to talk to each other in our lead developer’s lab.
